Staggered rotation of child objects

Hello all, maybe I’m asking a very obvious thing here but I still consider myself as a very beginner in coding.

So what I’m after is to have a staggered rotation of a child object compared to its parent.
In other words now my whole scene is rotating at the same time and I would like to have a small delay of its children following the parents rotation.
Would the easiest be to use the GSAP library for this?

Any help is more than appreciated.

Thanks in advance.
